Evaluation of the Relationship Between Eating Behaviour and Early Functional Clinical Outcomes in Total Knee Arthroplasty Patients

Özet

Aim: This study aimed to investigate the relationship between body mass index (BMI), clinical outcomes measured by the Oxford Knee Score (OKS), and eating behavior patterns assessed by the Adult Eating Behavior Questionnaire (AEBQ) in patients undergoing total knee arthroplasty. Materials and Methods: A total of 106 patients (95 women, 11 men) with a mean age of 60.2 ± 3.9 years (range: 48–65 years) were included in the study. Preoperative and postoperative BMI values and OKS were recorded. Eating behaviors were evaluated using the AEBQ. Patients were classified according to BMI categories and clinical OKS outcomes. Comparisons of AEBQ scores between groups were performed, and correlation analyses were conducted to assess the relationships between BMI, OKS, and eating behavior subscales. Results: The mean preoperative BMI was 31.5 ± 5.3 kg/m², which significantly decreased to 30.7 ± 5.1 kg/m² postoperatively (p < 0.001). The mean OKS improved significantly from 14.9 ± 6.5 points preoperatively to 30.8 ± 6.9 points postoperatively (p < 0.001). No significant differences were observed in AEBQ scores when patients were grouped according to BMI categories or OKS outcomes. Correlation analysis revealed a significant positive relationship between preoperative BMI and emotional overeating (p = 0.042, r = 0.198). A significant negative correlation was found between postoperative BMI and slowness in eating (p = 0.041, r = –0.199). Additionally, postoperative OKS showed a significant positive correlation with food selectivity (p = 0.035, r = 0.205). Conclusions: Although eating behavior patterns did not differ significantly across BMI classes or clinical OKS outcome groups, specific associations were identified between BMI, functional outcomes, and certain eating behavior traits. Preoperative BMI was associated with emotional overeating, while postoperative BMI was related to slower eating behavior. Furthermore, better postoperative knee function was associated with increased food selectivity. These findings suggest that eating behavior characteristics may be linked to both body weight and functional outcomes following total knee arthroplasty.
